Magnetoplasts are the highly fi lled polymer composite materials with ferromagnetic fi ller. They are used to produce magnetic products of complex shape. The value of the residual magnetic induction is directly proportional to volume percentage of magnetic powder in the matrix and grows with an increase in the degree of orientation of the magnetic particles. The technology of obtaining magnetoplastics based on polyamide 6 and products from them is described. To realize the maximum magnetic properties, the moulding of magnets is carried out in an external magnetic fi eld. The introduction of castor oil during the moulding of products helps to increase the residual magnetic induction by improving the conditions for the orientation of magnetic particles.
